"The watch is comfortable and the display is nice, but I have to wonder if 'it's me'.... clicked on the flashing lights, but they would never cut off. Luckily (I'm only guessing here) there are different batteries for the watch and the flashing lights, because the watch is still running. It seems I always get the products that don't function properly, and I hope it was only me that got one that wouldn't shut off.There were no specific instructions with it either - in fact, the instructions that came with the watch were generic and for one with a link band, which this watch doesn't have."
